Atheists, do you believe that science will someday be able to explain the origins of the universe?

seamlessly and undeniably? If so, how will they go about doing this? What evidence can possibly be found that indicates that there was no designer or creator behind the big bang and that the universe is spontaneous and ultimately uncaused? How can something unknowable ever become known without a doubt? Face it, eradicating God is a mountain of a task that science will likely never be able to do.
